The third and final WWDC product I want to talk about is - of course - OS X 10.9 Mavericks. While iOS 7 was clearly the focus of this year's WWDC, its venerable desktop counterpart certainly wasn't left behind. Apple announced OS X 10.9 Mavericks, the first OS X release not to carry the name of a big cat.

Selecting View > Show Path Bar will give you an always visible folder path if you really want one, but it's largely redundant since Cmd-clicking the window name provides the same navigation without taking up space the rest of the time.

Cmd-Shift-G will display an editable path field that you can type an absolute or relative path into (e.g. /Applications, Documents/foo.text) and open that folder on ENTER. (Doesn't seem to accept '..' to go up a level, but this is Finder after all.)

For bonus points, if you use Terminal then stick the following in your ~/.bash_profile, then type cdf to switch your current working directory to Finder's frontmost folder:

function cdf { # change current directory to front finder window/selection
cd "`osascript << EOF
try
tell application \"Finder\"
set sel to selection
if sel is not {} then
set f to item 1 of sel
if class of f is in {disk, folder} then
return POSIX path of (f as alias)
else
return POSIX path of (get container of f as alias)
end if
else if Finder window 1 exists then
return POSIX path of (get target of Finder window 1 as alias)
else
return POSIX path of (get desktop as alias)
end if
end tell
on error
return \"/\"
end try
EOF`"
}

To go the other way, just type 'open .' and your current working directory will appear in Finder.
